Koi Care Kennel, Inc.

Regular price $47.98


ProForm-C® is a broad spectrum treatment that is safe and effective for the control of diseases caused by Ichthyophthirius (ich), Costia, Trichodina, Chilodonella, Oodinium and fungal infections. It is a malachite green and formalin combination that is considerably less toxic to koi and goldfish than other similar products in the market.

Required treatment time is generally 3 days and bypassing the biofilter is not required. One quart treats a 3,200-gallon system three times and one gallon treats a 12,800-gallon system three times. For use with koi only"not for food fish.

The Benefits of ProForm-C:

  • The safest and most effective treatment for the control of diseases caused by Ichthyophthirius (ich), Costia, Trichodina, Chilodonella, Oodinium and fungal infections.
  • The ONLY MG&F treatment that can be used in water temperatures as low as 50 degrees (F), thus allowing you to treat in early Spring and late Fall. All other MG&F treatments CANNOT be used below 62 degrees (F).
  • Treatment is DAILY. Most other MG&F treatments are dosed once every three days. Dosing daily allows you to complete the treatment in 3 days instead of 9 days.
  • You DO NOT need to bypass your bio-filters, which allows a more comprehensive treatment of the entire pond system.
  • Less toxic to koi and goldfish than any other MG&F product on the market.

Important to Note:

  • ProForm-C should not be stored below 50ºF or above 110ºF
  • ProForm-C should not be used with salt levels over 0.05%
